2820

Overview

The Visaton 2820 is a miniature full-range loudspeaker featuring a Mylar diaphragm and a round metal basket. It has an impedance of 8 ohms, a continuous power rating of 0.3 W, and a maximum power handling capacity of 0.5 W. The unit operates with a frequency response starting at 38 Hz and delivers a sound pressure level of 92 dB. Its compact physical dimensions include a diameter of 2.3 cm (0.9 inches) and a depth suitable for flush or panel mounting in signal output equipment.

Feature Summary

• Miniature form factor with Mylar diaphragm construction
• General-purpose full-range electromagnetic transducer design
• Round metal basket structure for structural support

Applications

• Signal output in compact electronic equipment
• General purpose audio reproduction in small enclosures
• Portable device speaker integration

Procurement Notes

Verify the specific power rating requirements against the 0.3 W continuous and 0.5 W maximum specifications. Confirm that the 8-ohm impedance matches the amplifier output stage. Ensure the 2.3 cm diameter fits the designated mounting aperture. Check that the operating temperature range covers the intended environment. Validate the solder lug termination type for circuit board connection.

Selection Notes

Select this component when space constraints require a 2.3 cm diameter driver. Choose based on the need for a Mylar diaphragm for general-purpose fidelity. Consider the 8-ohm load compatibility with existing audio circuits. Evaluate the 92 dB sensitivity for required volume levels in small enclosures. Assess the mechanical depth to ensure proper fit within the housing.

Part Context

Visaton manufactures acoustic components including tweeters, woofers, and crossover filters. The 2820 belongs to their line of miniature speakers designed for signal output applications. This model represents a standard full-range solution for low-power audio tasks where size is a primary constraint.
